Assassin's Creed: Brotherhood is due out on 16th November this year.
That's according to a new trailer, which you can see below, that leaked onto YouTube earlier today.
According to the trailer, Brotherhood is set in Rome in 1503 AD, where there are lots of pigeons (reports that we're effectively live-blogging the CG while we write this are largely accurate).
Assassins, as ever, lurk in the shadows - and this time it does appear to be assassins plural, as protagonist Ezio Auditore is assisted by unseen supporters as he daringly approaches a Templar through a crowd of henchmen.
They all meet swift and unfortunate ends and then it really kicks off. It's worth watching the whole thing to see what happens.
Brotherhood is known to continue Ezio's story, and will also include multiplayer for the first time in the series.
